mr. whitaker, i was listening to miss lawrence. before i ask mr.misener some questions about amazon, and their operation i'm what is, if i'm a homeowner, how high up do i go in my property control? can someone fly 500 feet from my roof? >> so i think as, mr. geiger has -- >> i will ask all of you to please speak into the mic to move it closer. >> yeah. so i think, mr. geiger articulated earlier it is a bit unsettled. clearly if it is 500 feet above your house, it is federally regulated airspace. when federally regulated airspace was defined decades and decades ago there was no thought of a gray area but i think now we're probably facing a gray area. but by statute all airspace is federal airspace and regulate federally. >> so commercial drone is flying within three feet of my roof is that federally regulated airspace? >> you're pushing at those gray areas, yeah. >> i think we'll have to revisit that too. i mean presumably someone is flying into deliver fine chocolates and french bubbly to my neighbor, did i mention fine chocolates and french bubbly
